+# Display The Contents Of A Directory As A Tree
+
+The [`exa` utility](https://github.com/ogham/exa) is a speedy replacement for
+`ls` that offers some additional features. One of those extra features is the
+_tree_ display.
+
+By including the `-T` (or `--tree`) flag, `exa` will recurse into a directory
+and display the entirety of the contents as a tree.
+
+```bash
+❯ exa -T
+.
+├── folder1
+│  ├── cats
+│  │  └── sneaky
+│  └── dogs
+│     └── fido
+└── folder2
+   ├── cats
+   │  ├── oreo
+   │  └── sneaky
+   └── dogs
+      └── fido
+```
+
+You can target a specific directory:
+
+```bash
+❯ exa -T folder2
+folder2
+├── cats
+│  ├── oreo
+│  └── sneaky
+└── dogs
+   └── fido
+```
+
+See `man exa` for more details.
